Honda Hydro Parts

I just purchased a 90's honda 48" mower. I have checked a few places around town to see if they had parts and came up short. I was wondering if anybody knows a place online with parts. I need some air filters and blades. Any responses will be greatly appreciated.

John- i have a honda 52" walk behind, probably from the 90's as well. no luck at any honda powersports dealers- motorcycles, generators, etc. nearby? my dealer has had parts. they made those walk behinds awhile.

there is a guy on ebay that sell the air filters and oil filters, the air on my 18 horse is kinda funky looking. do a search on ebay for honda, air filter and reduce it by the outdoor power equipment category. you'll find several. as far as hydro parts, I'll try to remember and ask my local honda dealer.
